The drive-throughs may include one or both of a menu board and a speaker post. The communication system may include electronic storage and one or more hardware processors. The electronic storage may electronically store information. The information represents associations of individual voice communication channels with one or more communication groups. Individual ones of the one or more communication groups may be specific to one or more (types of) roles performed by employees in the quick-service restaurant. The associations include a first, second, third, and so forth association. The first association is between a first voice communication channel and a first communication group. The first communication group may be specific to (a first type of) roles in the quick-service restaurant that are related to the first drive-through lane. The second association is between a second voice communication channel and a second communication group. The second communication group may be specific to (a second type of) roles in the quick-service restaurant, and in some cases may be related to the second drive-through lane. The third association is between a third voice communication channel and the first and second communication groups. The fourth association is between a fourth voice communication channel and the first communication group and a third communication group. The third communication group is specific to (a third type of) roles in the quick-service restaurant that may be related to food production. The fifth association is between a fifth voice communication channel and the second and third communication groups. The sixth association is between a sixth voice communication channel and the first, second, and third communication groups. The seventh association is between a seventh voice communication channel and the third communication group. The one or more hardware processors are configured by machine-readable instructions to receive a first device-specific packet from a first communication device associated with a first crew member. The first device-specific packet is received during a first uplink time period and includes packetized uplink information based on audio information captured by the first communication device.

DETAILED DESCRIPTION

FIG. 1 illustrates a system 100 configured for managing voice communication channels used, e.g., by a crew of employees in a quick-service restaurant having one or more drive-through lanes. System 100 may be referred to as an intercom communication system, or as a communication system. In some implementations, system 100 may include one or more central communication devices 101, one or more information processing units 102, one or more processors 124, electronic storage 122, one or more base stations 103, one or more external resources 120, one or more user interfaces 140, one or more end-user communication devices 104 and/or other components.

The users of system 100 may include employees, staff members or crew members, managers and/or other stakeholders, and/or other groups of people interacting and/or otherwise working together. The users of system 100 may be divided into a set of communication groups. In some implementations, individual communication groups may be specific to one or more (types of) roles of employees in a quick-service restaurant. For example, a given communication group may be specific to a given role or type of role of people interacting and/or otherwise working together. In some implementations, individual communication groups may be specific to one or more locations in a work area and/or other localized area. In some implementations, individual communication groups may be specific to one or more responsibilities in a work area and/or other localized area. For example, the communication groups for a quick-service restaurant may include four communication groups: a first communication group may be specific to roles in the quick-service restaurant that are related to a first drive-through lane, a second communication group may be specific to roles in the quick-service restaurant that are related to a second drive-through lane, a third communication group may be specific to roles in the quick-service restaurant that are related to food production, and a fourth communication group may be specific to roles in the quick-service restaurant that are related to the front counter. Variations may use only one drive-through lane, and/or may combine the groups for food production and front counter. For example, the communication groups for a theater production may include different communication groups for stage crew, audio-visual crew, lighting crew, front-of-house crew, director, etc. System 100 may be used in other contexts where people work together, including but not limited to theme park ride management, medical operating room communications, football coach communications, factory floor communications, and/or other contexts.

Voice communication channels managed by system 100 may facilitate communication among and/or between specific (sets of) communication groups. By way of non-limiting example, FIG. 3A illustrates an exemplary set 301 of three communication groups that are specific to different (types of) roles and/or locations in a work area, such as a quick-service restaurant. The first communication group is indicated by the label “Communication group I”. The second communication group is indicated by the label “Communication group II”. The third communication group is indicated by the label “Communication group III”. Communication for different subsets of these three communication groups may use seven different voice communication channels as depicted. Communication to just the first communication group may use a first voice communication channel. Communication to just the second communication group may use a second voice communication channel. Communication to both the first and second communication groups may use a third voice communication channel “C3”. Communication to just the third communication group may use a seventh voice communication channel. Communication to both the first and third communication groups may use a fourth voice communication channel “C4”. Communication to both the second and third communication groups may use a fifth voice communication channel “C5”. Communication to the first, second, and third communication groups may use a sixth voice communication channel “C6”. In some implementations, a user in the first communication group could direct and/or transmit a voice message/communication to any of the communication groups, but would only receive voice messages/communication directed and/or transmitted to the first communication group (e.g., the user can select the first, third, fourth, or sixth broadcast channel, depending on which other communication groups are to be added/included). A user in the second communication group would only receive voice messages/communication directed to and/or transmitted to the second communication group (e.g., the user can select the second, third, fifth, or sixth broadcast channel, depending on which other communication groups are to be added/included). A user in the third communication group would only receive voice messages/communication directed to and/or transmitted to the third communication group (e.g., the user can select the fourth, fifth, sixth, or seventh broadcast channel, depending on which other communication groups are to be added/included). By way of non-limiting example, FIG. 3B illustrates an exemplary set 302 of four communication groups that are specific to different (types of) roles and/or locations in a work area, such as a quick-service restaurant. Exemplary set 302 is similar to set 301 of FIG. 3A, with an added fourth communication group, indicated by the label “Communication group IV”. Communication to just the fourth communication group may use a ninth voice communication channel. Communication to both the third and fourth communication groups may use an eighth voice communication channel “C8”. In some implementations, a user in the fourth communication group could direct and/or transmit a voice message/communication to any of the communication groups, but would only receive voice messages/communication directed and/or transmitted to the fourth communication group (e.g., the user can select the eighth or ninth broadcast channel, depending on which other communication groups are to be added/included). In this case, the user in the third communication group could additionally select the eighth voice communication channel.

Referring to FIG. 1 , central communication device 101 (also referred to as central communication hub) and/or information processing unit(s) 102 may be configured to communicate with one or more end-user communication devices 104 according to a client/server architecture, a point-to-point architecture, and/or other architectures. End-user communication device(s) 104 (also simply referred to as communication devices) may be configured to communicate with other communication devices 104 via central communication device 101, information processing unit(s) 102, and/or other components of system 100. Users may access system 100 via communication devices 104. Communication devices 104 may include a first communication device 104 a, a second communication device 104 b, a third communication device 104 c, and/or other communication devices. First communication device 104 a may be associated with a first user, second communication device 104 b may be associated with a second user, third communication device 104 c may be associated with a third user, and so forth. Communication devices 104 may be portable communication devices. In some implementations, communication between communication devices 104 may be performed on a local communications network, such as, by way of non-limiting example, a local area network. Alternatively, and/or simultaneously, in some implementations, the local communications network may include a personal area network. For example, the local communications network may be used in a restaurant, a service location, a theater, an office, a building, a construction site, and/or in other localized areas.

Central communication device 101 may include one or more of information processing units 102, electronic storage 122, a first antenna 101 a, a second antenna 101 b, and/or other components. In some implementations, central communication device 101 may be referred to as a (remote and/or fixed) communication device. In some implementations, central communication device 101 may be configured to facilitate localized communications in a local communications network among a set of communication devices 104, such as, by way of non-limiting example, first communication device 104 a, second communication device 104 b, third communication device 104 c, and/or other communication devices. In some implementations, individual antennas of central communication device 101 may be configured to operate in conjunction with individual transceivers that are included in central communication device 101 (not depicted). By virtue of having two separate antennas and two separate transceivers, communications by central communication device 101 may be improved (by way of non-limiting example, in terms of reliability, audio quality, and/or other quality factors) by providing different types of diversity. The different types of diversity may include one or more of antenna diversity, transceiver diversity, spatial diversity (e.g., if multiple antennas on central communication device 101 are disposed and/or positioned in different locations), frequency diversity, channel diversity, time diversity, and/or other types of diversity.

Communications between central communication device 101 and one or more communication devices 104 may be based on the exchange of packets of information that are formatted in one or more particular formats. As used herein, the direction from central communication device 101 to one or more communication devices 104 may be referred to as downlink and/or downstream. As used herein, the direction to central communication device 101 from one or more communication devices 104 may be referred to as uplink and/or upstream. Accordingly, information provided through uplink communication may be referred to as uplink information, information provided through downlink communication may be referred to as downlink information. In some implementations, packets may be formatted using a format based on the (IEEE) 802.11 family of standards. In some implementations, packets may have a proprietary format. In some implementations, downlink packets may be broadcast packets that are transmitted to multiple communication devices 104 at once. In some implementations, uplink packets may be device-specific packets that are transmitted by a particular communication device 104. Packetized communication may have overhead, e.g., due to the use of header information, which may reduce the efficiency of the communication. Broadcast packets may be more efficient than uplink packets, since information for multiple communication devices 104 may be transmitted at once, whereas uplink packets may only contain information from a single communication device 104.

Central communication device 101 may use different communication protocols, communication formats, and/or communication links to communicate with different ones (and/or different types) of communication devices 104 and/or other components of system 100. For example, central communication device 101 may use a primary (wireless) communication link to communicate with first communication device 104 a. In some implementations, central communication device 101 may use first antenna 101 a (and a corresponding transceiver) to transmit and/or receive information over the primary communication link, using a first frequency range. In some implementations, central communication device 101 may use second antenna 101 b (and a corresponding transceiver) to transmit and/or receive information over the primary communication link, using a second frequency range.

For example, central communication device 101 may use a secondary communication link to communicate with base station 103. In some implementations, communication via the secondary communication link may be based on the Ethernet family of standards. In some implementations, communication via the secondary communication link may be based on a proprietary format. In some implementations, communication over the secondary communication link may be point-to-point. In some implementations, communication over the secondary communication links may be supported in system 100 without the need or use of cellular networks or public networks.

For example, central communication device 101 may use a particular wireless communication link to communicate with one or more client communication devices 104, including but not limited to first communication device 104 a, second communication device 104 b, third communication device 104 c, and/or other communication devices. In some implementations, communication (in particular registration and configuration) via this wireless communication link may include communication based on a short-range wireless communication protocol, contact-less information, and/or near-field communication (NFC). In some implementations, central communication device 101 may use a separate antenna (not depicted) to transmit and/or receive information over this particular communication link. In some implementations, communication over this particular communication link may be supported in system 100 without the need or use of cellular networks or public networks.

Information processing unit(s) 102 may be configured by machine-readable instructions 106. Machine-readable instructions 106 may include one or more instruction components. The instruction components may include computer program components. The instruction components may include one or more of packet generating component 108, packet transmission component 110, packet receiving component 112, channel mapping component 114, audio mixing component 126, and/or other instruction components. In some implementations, one or more of the instruction components may be part of other information processing units, including but not limited to information processing units 102 a of base station 103.

Packet receiving component 112 may be configured to receive packets, including but not limited to broadcast packets, device-specific packets, and/or other packets. Receipt of packets may be scheduled, arranged, and/or otherwise timed in specific time periods. In some implementations, central communication device 101 may be configured to receive one or more device-specific packets. For example, packet receiving component 112 may receive multiple device-specific packets per time frame, such as a first, second, third, fourth, fifth, sixth, seventh, eighth, nineth, tenth, and/or other device-specific packets, e.g., from different communication devices 104.

For example, a first device-specific packet may be received by first central antenna 101 a, e.g., during a first uplink time period that occurs within a first time frame. The first device-specific packet may be received from first end-user communication device 104 a. The first device-specific packet may include packetized uplink information based on audio and/or video information captured by first end-user communication device 104 a. The audio and/or video information captured by the first end-user communication device may be part of audio communication (through system 100) between different users. The first device-specific packet may be targeted to a given communication group, such as, e.g., a first communication group. In some implementations, the first device-specific packet may have a given destination, such as, e.g., the first communication group. By way of non-limiting example, individual communication groups may be associated with one or more voice communication channels selected from a set of broadcast communication channels. Individual ones of the one or more communication groups may be specific to one or more (types of) roles of people interacting within a group of people, such as a crew of employees in a quick-service restaurant. For example, in reference to FIG. 3A, audio information in a device-specific packet targeted to the first communication group may be included in the first, third, fourth, and sixth broadcast channels.

Packet receiving component 112 may be configured to receive a second device-specific packet, e.g., during a second uplink time period that occurs within the first time frame or within a second time frame. In some implementations, the second uplink time period may occur subsequent to the occurrence of the first uplink time period. The second device-specific packet may be received from second end-user communication device 104 b. The second device-specific packet may include packetized uplink information based on audio and/or video information captured by second end-user communication device 104 b. The audio and/or video information captured by second end-user communication device 104 b may be part of audio communication (through system 100) between different users. The second device-specific packet may be targeted to a given communication group, such as, e.g., the second voice communication channel. In some implementations, the second device-specific packet may have a given destination, such as, e.g., the second communication group. For example, in reference to FIG. 3A, audio information in a device-specific packet targeted to the second communication group may be included in the second, third, fifth, and sixth broadcast channels.

Packet receiving component 112 may be configured to receive a third device-specific packet, e.g., during a third uplink time period that occurs within the first time frame, the second time frame, or within a third time frame. In some implementations, the third uplink time period may occur subsequent to the occurrence of the first and second uplink time periods. The third device-specific packet may be received from third end-user communication device 104 c. The third device-specific packet may include packetized uplink information based on audio and/or video information captured by third end-user communication device 104 c. The audio and/or video information captured by third end-user communication device 104 c may be part of audio communication (through system 100) between different users. The third device-specific packet may be targeted to a given communication group, such as, e.g., the third communication group. In some implementations, the third device-specific packet may have a given destination, such as, e.g., the third communication group. For example, in reference to FIG. 3A, audio information in a device-specific packet targeted to the third communication group may be included in the fourth, fifth, sixth, and seventh broadcast channels. And so forth for additional device-specific packets.

By way of non-limiting example, FIG. 4 illustrates an exemplary time frame 401 having a top portion and a bottom portion (using different sections of the same frequency range), with the top portion showing a first, second, and third through tenth time period (for device-specific packets ULS0, ULS1, ULS2, and ULS10 in chronological order). The bottom section shows the same packets being transmitted at a later time.

Referring to FIG. 1 , packet generating component 108 may be configured to generate packets, including but not limited to broadcast packets, downlink packets, device-specific packets, and/or other packets. In some implementations, downlink packets may include a first downlink packet, a second downlink packet, a third downlink packet, and/or other downlink packets. In some implementations, one or more broadcast and/or downlink packets may be generated by central communication device 101. In some implementations, one or more downlink packets may be generated by base station 103. Individual downlink packets may include packetized downlink information. By way of non-limiting example, (contents of) packetized downlink information may be based on audio and/or video information that was previously (e.g., in a previous time frame) included in one or more other packets, e.g., one or more device-specific packets and/or other uplink information. In some implementations, individual downlink packets may include packetized downlink information that is organized in a set of broadcast channels. In some implementations, individual downlink packets may have a target and/or destination indication that indicates a network destination in the local communications network for the included packetized downlink information. For example, the network destination may include and/or indicate one or more specific communication devices 104, one or more specific communication groups, and/or other destinations. The set of broadcast channels may include a first broadcast channel, a second broadcast channel, a third broadcast channel, and so forth. Individual broadcast channels may be used for previously received audio information that was targeted to one or more communication groups that are associated with one or more voice communication channels selected from a set of broadcast communication channels. For example, the first broadcast channel may be used for audio information targeted to the first communication group (in accordance with exemplary set of communication groups 301 of FIG. 3A, and the corresponding associations between individual voice communication channels and subsets of the set of communication groups). For example, the second broadcast channel may be used for audio information targeted to the second communication group (in accordance with exemplary set of communication groups 301 of FIG. 3A). For example, the third broadcast channel may be used for audio information targeted, at least, to one of the first and second communication groups (in accordance with exemplary set of communication groups 301 of FIG. 3A). For example, the fourth broadcast channel may be used for audio information targeted, at least, to one of the first and third communication groups (in accordance with exemplary set of communication groups 301 of FIG. 3A). For example, the fifth broadcast channel may be used for audio information targeted, at least, to one of the second and third communication groups (in accordance with exemplary set of communication groups 301 of FIG. 3A). For example, the sixth broadcast channel may be used for audio information targeted, at least, to one of the first through third communication groups (in accordance with exemplary set of communication groups 301 of FIG. 3A). For example, the seventh broadcast channel may be used for audio information targeted to the third communication group (in accordance with exemplary set of communication groups 301 of FIG. 3A). In some implementations, device-specific packets may be generated by individual communication devices 104.

By way of non-limiting example, FIG. 4 illustrates an exemplary time frame 401 having a top portion and a bottom portion (using different sections of the same frequency range), with the top portion showing a first downlink packet labeled “BP0”, which includes the first through tenth broadcast channels. The indicated use of ten broadcast channels is exemplary and not intended to be limiting.

Referring to FIG. 1 , in some implementations, packet generating component 108 may be configured to generate downlink packets that include packetized downlink information that is organized in a set of dedicated channels. In some implementations, individual dedicated channels may have a target and/or a destination that is a specific communication device 104, such that the audio information on an individual dedicated channel excludes audio information received from the specific communication device 104. As a result, the user of the specific communication device 104 will not receive an echo through the individual dedicated channel of their own audio. For example, a first dedicated channel may include the same audio information as the first broadcast channel, minus the audio information received from first communication device 104 a (for example, if the audio information from first communication device 104 a targeted the first communication group, the first dedicated channel would include the audio information targeted to the first communication group). For example, a second dedicated channel may include the same audio information as the second broadcast channel, minus the audio information received from second communication device 104 b (for example, if the audio information from second communication device 104 b targeted the second communication group, the second dedicated channel would include the audio information targeted to the second communication group). For example, a third dedicated channel may include the same audio information as the third broadcast channel, minus the audio information received from third communication device 104 c (for example, if the audio information from third communication device 104 c targeted the third communication group, the second dedicated channel would include the audio information targeted to the third communication group), and so forth.

By way of non-limiting example, FIG. 4 illustrates an exemplary time frame 401 having a top portion and a bottom portion (using different sections of the same frequency range), with the top portion showing a first downlink packet labeled “BP0”, which includes the first through tenth dedicated channels, in addition to broadcast channels. The indicated use of ten dedicated channels is exemplary and not intended to be limiting. The bottom portion also shows downlink packet labeled “BP0”, which may be transmitted at a different time.

Referring to FIG. 1 , packet transmission component 110 may be configured to transmit packets, including but not limited to downlink packets, device-specific packets, and/or other packets. Transmission of packets may be scheduled, arranged, and/or otherwise timed in specific time periods. As used herein, time periods are periods of time, having a specified and/or limited duration. A set or sequence of time periods may be scheduled, arranged, and/or otherwise timed to occur in particular time frames. In some implementations, different periods in a set or sequence may not overlap. For example, the duration of individual time frames may be between 1 and 3 ms, between 4 and 6 ms, about 5 ms, between 5 and 10 ms, between 8 and 12 ms, about 10 ms, about 15 ms, between 10 and 20 ms, and/or another duration. In some implementations, individual time periods may include time slots.

In some implementations, downlink packets may be transmitted by central communication device 101. For example, a first downlink packet may be transmitted via first central antenna 101 a (of the first central transceiver) of central communication device 101 to a set of end-user communication devices 104. For example, a second downlink packet may be transmitted via second central antenna 101 b (of the second central transceiver) of central communication device 101 to the same set of end-user communication devices 104. In some implementations, the first and second downlink packets may be transmitted in different time periods during the same time frame. In some implementations, individual time frames may include two downlink packets. In some implementations, individual time frames may include more than two downlink packets. Transmission of the first downlink packet may use a first channel of a first frequency range. As used herein, channels are designated sub-ranges within a frequency range, commonly having equal bandwidths and/or equally-spaced-apart bandwidths. For example, transmission of the second downlink packet may use a second channel of the first frequency range (wherein the first channel is different from the second channel). For example, the frequency range may be 900 MHz, 1.9 GHz, 2.4 GHz, 5 GHz, and/or at least 5 GHz. In some implementations, individual channels of a particular frequency range may use a 5 MHz bandwidth per channel, 10 MHz, 20 MHz, 40 MHz, and/or use another bandwidth per channel. By way of non-limiting example, for the 5 GHz frequency range, so-called channel 32 may range from 5150 to 5170 MHz, channel 46 may range from 5210 to 5250 MHz, and so forth.

In some implementations, device-specific packets may be transmitted by individual communication devices 104. For example, a first device-specific packet may be transmitted via an antenna 105 a (of a transceiver) of first end-user communication device 104 a. For example, a second device-specific packet may be transmitted via an antenna 105 b (of a different transceiver) of second end-user communication device 104 b. For example, a third device-specific packet may be transmitted via antenna 105 c (of yet a different transceiver) of third end-user communication device 104 c. In some implementations, the first, second, and third device-specific packets may be transmitted in different time periods and/or during the same time frame. For example, transmission of the first device-specific packet may use the first channel of the first frequency range. For example, transmission of the second device-specific packet may use the first channel of the first frequency range. For example, transmission of the third device-specific packet may use the first channel of the first frequency range.

Channel mapping component 114 may be configured to determine mappings between individual communication groups (as targeted by device-specific packets) and individual broadcast channels. For example, the selection of individual broadcast channels may be in accordance with a particular selection from the set of communication groups. In some implementations, channel mapping component 114 may be configured to determine mappings between individual voice communication channels (as targeted by device-specific packets) and individual dedicated channels in downlink packets. In some implementations, determinations by channel mapping component 114 may be based on a particular set of communications groups, as for example depicted in FIGS. 3A-3B-3C-3D.

Audio mixing component 126 may be configured to mix audio information from different communication devices 104 (as received through device-specific packets) into individual broadcast channels, dedicated channel, and/or other channels. In some implementations, audio mixing component 126 may operate based on determinations made by channel mapping component 114. By way of non-limiting example, FIG. 3C illustrates an exemplary set 303 of four communication groups that are specific to different (types of) roles and/or locations in a work area, such as a quick-service restaurant. The first communication group is indicated by the circle with label “C1” in the center, the second communication group is indicated by the circle with label “C2” in the center, the third communication group is indicated by the circle with label “C3” in the center, and the fourth communication group is indicated by the circle with label “C4” in the center.

Communication to the first communication group may use a first, fifth, and eighth voice communication channel. Communication to the second communication group may use a second, fifth, and sixth voice communication channel. Communication to the third communication group may use a third, sixth, and seventh voice communication channel. Communication to the fourth communication group may use a fourth, seventh, and eighth voice communication channel. Users interested in communication to both the first and second communication groups may select the fifth voice communication channel “C5”. Users interested in communication to both the second and third communication groups may select the sixth voice communication channel “C6”. Users interested in communication to both the third and fourth communication groups may select the seventh voice communication channel “C7”. Users interested in communication to both the fourth and first communication groups may select the eighth voice communication channel “C8”.

The method of claim 11, wherein the first downlink packet further includes packetized downlink information organized in a set of dedicated channels, wherein the set of dedicated channels includes: a first dedicated channel used for audio information received in device-specific packets targeted, at least, to a first subset of the individual voice channels associated with the first subset of communication groups according to at least a first individual association, minus audio information received from the first communication device, such that the first person will not receive an echo through the first dedicated channel, a second dedicated channel used for audio information received in device-specific packets targeted, at least, to a second subset of the individual voice channels associated with the second subset of communication groups according to at least a second individual association, minus audio information received from the second communication device, such that the second person will not receive a second echo through the second dedicated channel, and a third dedicated channel used for audio information received in device-specific packets targeted, at least, to a third subset of the individual voice channels associated with the third subset of communication groups according to at least a third individual association, minus audio information received from the third communication device, such that the third person will not receive a third echo through the third dedicated channel.
 15. The method of claim 11, wherein the first downlink packet is transmitted at least twice in the same time frame.
 16. The method of claim 15, wherein two transmissions of the first downlink packet within the same time frame occur on different channels of a particular frequency range.
 17. The method of claim 11, wherein the first, second, and third uplink time periods do not overlap in time.
 18. The method of claim 11, wherein a first type of roles in a quick-service restaurant are related to a first drive-through lane, wherein a second type of roles in the quick-service restaurant are related to a second drive-through lane, wherein a third type of roles in the quick-service restaurant are related to food production.
 19. The method of claim 11, wherein the first uplink time period occurs within a first time frame, wherein the second uplink time period occurs within a second time frame, and wherein the third uplink time period occurs within a third time frame.
 20. The method of claim 11, wherein the first downlink packet is transmitted within a given time frame subsequent to the first, second, and third time frames, wherein individual ones of the first, second, and third time frames have individual durations between 5 and 15 ms.
